Member Enumeration Documentation

◆ EAxisBoundsKind

enum ROOT::Experimental::RPadUserAxisBase::EAxisBoundsKind

Types of axis bounds to respect by the painter.

Non-fixed ones will be updated by the painter once the first paint has happened.

Enumerator
kAxisBoundsAuto 

no defined axis range; the painter will decide

kAxisBoundsBegin 

the axis begin is to be respected by the painter.

kAxisBoundsEnd 

the axis end is to be respected by the painter.

kAxisBoundsBeginEnd 

the axis minimum and maximum are to be respected by the painter
